I am the LaFarge SJ Professor of Public Policy at the McCourt School of Public Policy, Georgetown University. I am also a senior fellow in Economic Studies at Brookings, an AIR Fellow at the American Institutes for Research, and a former Chief Economist at the US Department of Labor. I have authored or edited a dozen books on US labor markets, especially for low-wage workers, along with dozens of peer-reviewed articles. My specific interests include education and job training as well as immigration, minimum wages and racial disparities.
